The Mogao Grottoes located in Gansu Province of north-western China consist of 492 cells and cave sanctuaries carved into the cliffs above the Dachuan River in Mogao. A UNESCO World Heritage Site, they comprise the largest, most richly endowed, and oldest treasure house of Buddhist art in the world. However, for preservation and conservation reasons most of the caves are now closed to the public. This chapter discusses the range of technologies currently available for the virtual representation of Cave 220, just one of the many caves located at this site. In particular, the chapter focuses on the latest prototype, developed by the authors called Pure Land UNWIRED which uses a virtual reality platform specifically designed for a unique single user full-body immersive virtual reality experience. The discussion includes technical and evaluative analysis of this prototype.
